I know this part....but, how do you correct it...how do u add or delete the old clerk and then reprogram.....the register is locked up and will not do anything but show e32 error as soon an you turn . it on

try to do that already, the cash register is about 2-3 years old....it's locked up and will not do anything AT ALL!!!!! buttons not responding just the key..... is there a system reboot/reset...already tried to reinitialize it with the same results!!!
